It is instructive to compare the general expressions we have obtained
in sections REF  and REF  with the form of the
BRST transformations and
Lagrangian discussed in [1]}. Scaling up the Lagrangian in
[1]} by a factor of 2 in order to agree with our normalisation,
it becomes
\({\cal {L}}^{\prime } = {\cal {L}}(h_{\mu \nu },\varphi , B_{\mu \nu }) + \hat{\cal {L}^{\prime }}\,,\)
